The invention provides a new 1,4-diazepine derivative and a pharmacologically acceptable salt thereof, a process for preparing it and the pharmaceutical use. The compound and the salt have an excellent medical activity.
In recent years, a platelet activating factor (hereinafter referred to simply as PAF) has attracted much attention and its relationship with various diseases is now being clarified. Now, it has been assumed that PAF takes part in not only inflammation, but also DIC, endotoxin shock, asthma, ulcers in alimentary canal, hepatisis and the rejection at the time of organ transplantation. In addition, attention has been drawn to as a mediator which is one of allergic reactions.
Under these circumstances, there have been made investigations on compounds having the anti-PAF activity. Among these compounds, a 1,4-diazepine compound having the anti-PAF action has been proposed, for example, in Japanese Laid-open Patent Application No. 63-33382. However, a satisfactory anti-PAF agent which is adapted, particularly, for allergies such as asthma has not been developed yet.
Accordingly, we have continued investigations and studies over a long term with respect to 1,4-diazepine derivatives which have not only an excellent PAF-inhibiting activity, but also a long activity.

The respective steps indicated above are briefly illustrated in the following.
First Step
2-Bromopropionyl bromide of the formula (XI) is subjected to condensation reaction with the compound of the general formula (X) by usual manner to obtain the compound of the general formula (XII).
This reaction is carried out in a two-phase system (under Schotten-Bauimann conditions) of an organic solvent such as, for example, toluene, benzene, xylene or the like in the presence of either an alkali hydroxide such as sodium hydroxide, potassium hydroxide or the like or a base such as sodium hydrogencarbonate, potassium hydrogencarbonate or the like.

Second Step
In this step, ammonia gas is introduced into the compound of the general formula (XII) by usual manner to obtain the compound (XIII).
This reaction should preferably be effected at low temperatures ranging, for example, from 30° C. to 100° C.
The reaction is carried out in a solvent-free condition or by the use of an appropriate solvent which does not take part in the reaction and is selected from ethers such as tetrahydrofuran, dioxane and the like, ethyl acetate, chloroform, methanol, ethanol, pyridine and dichloroethane.
Third Step
In this step, the compound of the general formula (XII) is subjected to dehydration reaction by the usual manner thereby causing cyclization to obtain the compound of the general formula (XIV).
One of the procedures is particularly described. The compound is dissolved in an appropriate solvent not taking part in the reaction such as, for example, benzene, toluene, xylene, pyridine or the like, to which one equivalent of an acid catalyst such as acetic acid, silica gel or the like. While removing the water produced as the reaction proceeds by the use of a dehydrator or by means of the Dean Stark apparatus, the reaction system is heated.
Fourth Step
This step is one wherein phosphorus pentasulfide is added to the compound of the general formula (XIV) for reaction to obtain the compound of the general formula (XV).
This reaction is carried out in a solvent such as pyridine, dimethoxyethane, diglymes, tetrahydrofuran, toluene, benzene, xylene or the like. The reagent may be, aside from phosphorus pentasulfide, the Lauson reagent, (2,4-bis(4-methoxyphenyl9-1,3-dithia-2,4-diphosphetan-2,4-disulfide). In some case, the reaction is carried out in the presence of a base such as sodium hydrogencarbonate.
Fifth Step
This step involves the reaction wherein acetohydrazide is reacted with the compound of the general formula (XV) to cause the cyclization reaction, thereby obtaining compound of the general formula (XVI).
This reaction is effected by heating acetohydrazide in a solvent which does not take part in the reaction such as, for example, dioxane, dimethoxyethane, diglymes or the like or in a solvent-free condition. Alteratively, hydrazide hydrate is reacted in a solvent such as methanol or ethanol and the resultant hydrazide is reacted to ethyl ortho-acetate to obtain an intended product. Still alternatively, hydrazide may be reacted with acetyl chloride or acetic anhydride and the resultant product is dehydrated to obtain compound (XVI).
Sixth Step
This step is one wherein the compound of the general formula (XIV) is hydrolyzed by usual manner to obtain the compound of the general formula (XVII).
This reaction proceeds according to known procedures. For instance, heating in the presence of potassium hydroxide, sodium hydroxide, sodium ethoxide, sodium methoxide, potassium ethoxide, potassium methoxide or the like results in the compound of the general formula (XVII).
For the reaction, solvents may be used including alcohol solvents such as methyl alcohol or ethyl alcohol, tetrahydrofuran, dimethoxyethane or hydrous solvents.

The compound of the general formula (XVII) is a novel compound and is an important intermediate for obtaining final compounds having good anti-PAF activity. More specifically, the final compound prepared through the intermediate (i.e. compounds of the general formula (I) wherein R1 is a hydrogen atom and R2 is a methyl group) exhibits unexpectedly high anti-PAF activity than known 1,4-diazepine compound. In this sense, the compounds of the general formula (III), of which those of the formula wherein R1 is a hydrogen atom and R2 is a lower alkyl group, particularly a methyl group, are very valuable as intermediates.
The intermediates have asymmetric carbon and thus optical isomers exist. In the practice of the invention, dl products may be resolved into optically active products, if desired.
Th resolution may be performed at the stage of the compound of the general formula (XIII) wherein an optical resolving agent such as (+)-tartaric acid, (+)-camphoric acid, (+)-dibenzoyltartaric acid, (+)-10-camphorsulfonic acid, (+)-mandelic acid or the like may be used for the resolution. Alternatively, at the stage of the compound of the general formula (III) or (XVII), the resolution may be possible using an optical resolving agent such as dibenzoyl-D-tartaric acid or dibenzoyl-L-tartaric acid. Still alternatively, when using a column for optical isomer resolution such as, for example, a chiral(?) polyamide silica gel HPLC (elute: tetrahydrofuran-hexane), the resolution at the stage of the compound of the general formula (XIII), (XVII) or (III) is possible.
The other compounds than those described for the processes for their preparations can be obtained in the same way, except for changing starting materials.
